Solid State Disk (SSD) drive
Table 2–20 shows representative byte-wide memory devices that can be installed in the byte-wide socket.
The table gives examples of generic part numbers, the size of the device (K bytes), and the DIP package
pin count. It also lists the SSD device type, used by the Ampro Solid State Disk (SSD) Support Software
to identify memory devices.

The pinout of the 32-pin socket can be configured to comply with both the 28-pin and 32-pin JEDEC
standards. You can install a 28-pin device in the 32-pin socket. Install the 28-pin device with pin 1
oriented to the socket’s pin 3, as indicated in Figure 2–7.
